Is there utility to associate one EPM Document to several WTPart in bulk? We've got approximately 1200+WTParts that fall into this category

I have one EPMDocument (AutoCAD) and it is associated to 9 WTParts, one of them is the Owner, the others are Contributing Content.

We have a utility that relies on EPMDocument that is the owner link to determine what the name & number should be for the WTPart.

I am wondering Is there utility/way so the other eight WTParts get the appropriate name/number.
